  Also remember to glue the hinge into both the movable and non-movable surface at the same time. Dry assemble the parts, make sure the hinges are centered, bend the surface to full deflection, then wick thin CA into the center of the hinge. Do all the hinges on one side, then bend the surface the other way and repeat. Don't go back and add glue to "make it stronger", the CA will not wick into the joint and can form a sharp ridge in the center which will cut the hinge over time.  Have some paper towels and debonder or acetone ready in case any CA that runs out of the joint and onto the covering. I have been told this can happen, it never happens to me

    Xavier-
    I have used a crayon from my sons toy box, sharpened, and drawn along the hinge line.  This not only serves as an alignment point, but also as a release agent for the glue.  I guess I should also note I haven't used that method on most of my planes ( just wicked in CA at the hinge line, let dry, and flex vigorously back and forth ) with great results too.  You shouldn't worry too much about making the hinge stiff - just be sure you are using THIN CA!! :-)

      Hi guys,

      I am about to install the CA hinges (fiberglass) on two of my winter projects and I would appreciate any recommandations on the proper procedure to do it. I have the tight slots done. I am worrying about the glue making the hinge stiff. How do I ensure the glue doesn't go in the flexing area ?

      Note that these are 2 sport planes that I am using to improve my building skills before moving on to pattern plane building next year. I have been flying second hand pattern planes.

      Thanks

      Xavier
